Plant Machines, of which the following is a specification; e V

The primary object of the present invention is the provision of a ,machine that is readily pushed over the field for digging up the ground between the rows of vegetables, such as onion plants, the ground being rolled subsequently to the digging operation.

A further object of the invention is the provision of a cultivator for onion plants whereby the soil between the rows is easily and quickly mellowed and rolled leaving the same in a soft, smooth condition.

A stillfurther'object of the device is to provide a combined cultivator and roller for planted fields having a self-cleaningmeans for theground-digging members, the device bein s1m le in construction. eas and inex- I? i penslve. .to manufacture. v

;:With these general ob'ects -in view and othersfthat will appear as the nature. of the invention is better understood," the same consists in the novelconjstructiomcombination, and arrangementofparts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in a the appended claims.

In the drawings forming apart of this application and in which like designating .characters refer to corresponding parts throughout the several views,

Figure 1 is a side elevation of the invention with a portion of the handles broken away,

Figure 2 is a front elevation thereof,

Figure 3 is an enlarged sectional detail view taken upon line IIIIII of Figure 1, and

Figure 4 is an enlarged sectional view taken upon line IV-r-IV of Figure 1.

Referring more in detail to the drawing, the invention broadly consists of a roller 10 journaled by means of an axle 11 between two side rails 12 having handle portions 13 at their upper ends for pushing the device over the ground. The roller 10 is provided with a plurality of toothed disks 14 axially arran ed thereon in equal spaced relations for digging into the ground during the Specification of Letters Patent.

travel of the device, a ground-engaging roller 15 being journaled in rearwardly projectlng struts 16 for rolling down the ground after the toothed disks 14: havecut up and I mellowed the surface thereof.

a transverse rod 18 between the-side rails 12 at the point of connection between the said side rails 12 -and the struts l6, the forwardlower ends 19 of said hooksabeing broadened and in planesat opposite sides of -the toothed disks 14:. ,:Bars 20. are secured to the opposite sides ofthe hooks -17-'by bolts 21 7 for causing all of the; books 117 to move simultaneously.=

Uprightbolts 22 are pivoted tov atransverse rod 23 between the side rails 12 and passed through V bosses }24s of the hooks 17. Each bolt'22 has an-encircling spring 25 outwardly of its hook- 17' and an encircling r v to A plurality of hooks 1-7 are pivoted upon spring 26 inwardly thereof, whereby the-said hooks are resiliently positioned intermediate the ends of thebolts 22.;a-AV pull Jrod27 is pivoted at its lower end tofeyes 28 carried by if, 51 the two central hooks 17,2the upper endof-the rod 27 having a handl 29, The rod 27; freely extends through a bracket 30 and has spaced .p'airs;.of".lugs forming grooves :31 andi 82 adapted for adustably Qengaging the"; rack.- 30 when the rod 27, is adjusted in-its raised or lowered positionw Pulling of the rod'27 to-engage the groove 31 in the bracket 30 positions the hooks 17 uppermost above the level of the disk 1a while the release .ofthe rod 27 causes the springs. 25 to position the pointed ends 19 substantially on a plane with the periphery of the toothed disks 14:. By lowering the rod 27 to engage the groove 32 with he;

bracket 30 the'hook ends 19 are positioned inwardly toward the roller 10, between and outwardly of the toothed disk 14. The forward movement of the machine forces the teeth 14 into the soil by pressing uponthe handles 13," the periphery of the roller 10v limiting the extent to which the teeth may enter the soil while the roller 15 follows over the ground and smooths the same. Any weeds that are taken up during the travel r a of the machine will be prevented from being the device by reason of the hooks 17 as the ends 19 thereof will engage the weeds and will act to clear the teeth 14 durin opera- I carried along and deposited forwardly of resilient wherever the rod 27 may be adjusted because of the engaging springs and 26.

The complete operation vof the invention will be fully understood from this detailed shown and described is what is believed to be the preferred embodiment thereof, it is nevertheless to be understood that various forms, modifications and arrangements of the parts may be made without departing from the spirit and scope of the invention a as claimed.

1. A device of the class described comprising side rails, a roller journaled between the lower ends thereof, a plurality of toothed disks carried by the roller adapted for engaging the ground outwardly of the roller during the travel of the device, a ground roller journaled upon said side rails at the rear of the machihe and adjustable cleaning means for said toothed disk.

2; A device of the class described eomprising sidefrails, a roller journaled between the lower ends thereof, toothed disks axially carried by the roller equally spaced apart and adapted for engagingin the surface of the ground, pivoted hooks carried by the side rails having relative movement in planes between said toothed disks; and a follow-up roller mounted beneathsaid side rails.'-

3. A device of the class described comprising side rails, toothed disks equally spaced apart journaled for simultaneous rotation between the lower ends of said rails, a follower roller beneath said side rails rearthe outer periphery of the mouse wardly of said disks, aplurality of hooks pivoted between the side rails adapted for movement in planes at different sides of said disks, connecting'means between said hooks whereby the latter are adapted for simultane'ous movement and resilient positioning means for the hooks, a plurality of bolts pivoted atrtheir lower ends between said rails and freely projecting through said hooks, encircling springs around said bolts engaging the opposite sides of the hooks whereby the hooks are normally positioned with their lower free ends substantially in a plane with the outer periphery of the disks.

4. A device of the class described comprising side'rails, toothed disks equally spaced apart journaled for simultaneous rotation between the lower ends of said rails, a follower roller beneath said side rails rearwardly of said disks, a plurality of hooks pivoted between the side rails adapted for movement in planes at different sides of said disks, connecting means'between said hooks whereby the latter are adapted for'simultaneous movement, resilient positioning means for the hooks, a plurality of bolts pivoted at their lower ends between said rails and freely projecting through said hooks, encircling springs around said bolts engaging the opposite sides of the hooks whereby the hooks are normally positioned with their lower free ends substantially in a plane with V disks, a rod piv oted at its lower end to said hooks and extending upwardly between the said rails and provided with spaced grooves adjacent its upper end" and a bracket carried by the rails through which said rod projects adapted for adjustable engagement therewith when the hooks are in their upper or lowered position. In testimony whereof I aflix' my signature.
